Iattain thisiobject by embedding rods or wire of iron or other suitable materialof greattensile strength within thecon'crete, and my invention consists in the mode of placing' the-rodsor 'wire, and intheapparatus employed .-therefor, and in m'inor changes necessitated:thereby. "To avoid'con- 3 .fusiomthemods orlwire so applied, is termed throughoutythe specification bond iron.v In carrying out my invention, the bond iron is first coiled about a flanged spool or reel,which revolves upon a fixed, circular;- 0 rim-bearing. ,From this spoolthe bond iron is withd rawn by th'cforWard action, of the mold, its'move'ment being partly controlled and directed byhand. It becom'es a spiral as it leaves the reel, thedistancebctween' the several rings thereof, and its diameter also, are regulated by hand upon a cage, and also -.by gui'des,which heroinafterare merc fully described. This spiral, as the molds move forward, is left behind, and gradually becomes embedded in the concrete, where it acts benef ficially in giving tensile strength to the pipe in its resistance to the pressure of the fluid it contains, and in distributing overmore area any local pressure from the outside. Where plates are used (as described in Patent No. 353,500), in order to meet the changes necessitated by the introduction of the bond iron, they have to be passed thm'ngh'the center of the circular rim-bean ing. In order to prevent them 't'rom' too greatly obstructing the process of tamplug, their ends are imnpomrily closed together;

In order to meet the requirementsfof this new method, thedraft beam I, whtch connects 5 the shaper with the main or center' mold, is" curved'so as to make monitor the reel-and,

guides project to the rear, which further control' the position of -thebondiron untilit becomes sufiiciently secured in the concrete.-
